sps Video delay
This sets the minimum video delay of the
card.
In info this block reports back the current
delay in nanoseconds. This will vary with
the incoming video standard.

sps audio delay
The audio delay is given in audio samples.
Audio delay is always given relative to
video.

<Y> <Cb> <Cr>) ) Internal video generator.
The video generator will be activated in two
different ways: If selected as a fallback
option the generator will generate the
selected pattern when the other input(s) are
missing, and then use the video settings from
the last external source present. It can also
be selected as the main input in cho 1, in
which case its own video settings will also
be used.

Error counting. The count itself is reported
in info. Errors can be masked off and not
counted; this is the purpose of the mask. The
counter itself is 16b and will wrap around,
but can also be reset by issuing reset.

mtx 0 (size 10:8) controls the audio matrix;
outputs 0-7 are embedded sound; inputs 0-7
are de-embedded audio, 8=1kHz sine,

Note: Any combination of the three basic
commands are allowed, for instance the
following command to set up a 10x10 audio
matrix in a single line:
